Description

Technical Field

[0001] The utility model relates to the technical field of reducer gear rings, in particular to a wear-resistant reducer gear ring. Background Art

[0002] In the field of mechanical industry, reducer is a widely used device that increases output torque by reducing the speed of input power. One of the core components of reducer is the ring gear, which is subjected to continuous friction and impact loads during the power transmission process. Therefore, the wear resistance and service life of the ring gear directly affect the performance and reliability of the reducer.

[0003] The shortcomings of the existing reducer gear ring are mainly reflected in the following aspects:

[0004] Insufficient wear resistance: Traditional gear ring materials are prone to wear during long-term use, especially under high load and high-speed operation conditions, the wear of the gear ring will be more serious, which not only reduces the performance of the reducer, but also shortens its service life.

[0005] Difficulty in maintenance and replacement: In traditional reducer designs, the gear ring is usually connected to the reducer body by threaded connection or other fixing methods. This design is time-consuming and laborious to remove and replace the gear ring, especially after the reducer has been running for a long time or working in a harsh environment, the thread may rust or be damaged, making maintenance and replacement more difficult.

[0006] Therefore, there is an urgent need for a new wear-resistant reducer gear ring to solve the above problems. This new gear ring should have higher wear resistance and be able to maintain good performance and a longer service life under various working conditions. At the same time, it should be designed to be easy to maintain and replace to reduce maintenance costs and improve work efficiency. To this end, the utility model proposes a wear-resistant reducer gear ring to solve the above problems. Utility Model Content

[0007] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a wear-resistant reducer gear ring to solve the problems raised in the above background technology.

[0008] To achieve the above object, the technical solution of the utility model is implemented as follows: a wear-resistant reducer gear ring, comprising a gear ring, a wear-resistant ring and a clamping assembly, wherein the outer surface of the gear ring is connected with the wear-resistant ring, through grooves are respectively provided in both sides of the gear ring, and slide grooves are respectively connected in the through grooves up and down, and clamping grooves are respectively provided in both sides of the wear-resistant ring, one end of the clamping groove faces the gear ring, and the other end of the clamping groove is connected with a through hole, and the clamping assembly is arranged in the through grooves on both sides of the gear ring;

[0009] The clamping assembly includes a clamp, a slider and a spring. There are two clamps in total. The two clamps are respectively slidably arranged in the through slots. One end of the clamp is inserted into the clamp slot. The clamp is adapted to the shape and size of the clamp slot. Slides are respectively fixed on the upper and lower parts of the clamp. The other end of the slider is slidably placed in the slide slot. A spring is connected between the other end of the slider and the inner wall of one side of the slide slot.

[0010] The wear-resistant ring is composed of a hard alloy layer and an additive mixed layer. The hard alloy layer is arranged on the outer layer of the wear-resistant ring, and the additive mixed layer is arranged on the inner layer of the wear-resistant ring.

[0011] Preferably, a keyway is provided on the top of the wear-resistant ring for engaging with a raised key block of the reducer housing.

[0012] Preferably, one end of the through groove is communicated with the outside.

[0013] Preferably, one end of the card slot is connected to the outside.

[0014] Preferably, the other end of the through hole passes through the wear-resistant ring and is connected to the outside.

[0015] Preferably, the cemented carbide layer is a nickel-based alloy plating layer.

[0016] Preferably, the additive mixed layer is composed of silicon carbide or silicon nitride wear-resistant additives.

[0017] The beneficial effects of the utility model are embodied in:

[0018] Fast and convenient assembly and disassembly: Through the design of the clamping assembly, during assembly, the clamp can be automatically ejected into the slot by the elastic force of the spring, realizing fast and easy assembly of the wear ring. During disassembly, only a rod-shaped workpiece is inserted into the through hole and the clamp is pushed back into the through slot to achieve disassembly. This design is more convenient than the traditional threaded fixing method, especially when frequent replacement or maintenance is required.

[0019] Improve wear resistance and service life: The wear-resistant ring is composed of a carbide layer and an additive mixed layer, wherein the carbide layer is a nickel-based alloy plating layer, and the additive mixed layer is composed of wear-resistant additives such as silicon carbide or silicon nitride. This composite material structure greatly enhances the wear resistance of the gear ring and extends the service life of the reducer.

[0020] Prevent rust and improve reliability: The traditional threaded fixing method is prone to rust, which makes it difficult to disassemble. The clamping method adopted in this design avoids the rust problem, thereby improving the reliability and maintenance convenience of the reducer gear ring.

[0021] In summary, this wear-resistant reducer gear ring not only shows high efficiency and convenience during assembly and disassembly, but also significantly improves wear resistance and reliability through its unique material and structural design. It is suitable for various industrial environments, especially in situations where frequent maintenance or replacement of parts is required. BRIEF DESCRIPTION OF THE DRAWINGS
